GFI KerioControl NG521
The GFI KerioControl NG521 is a 1U rackmount appliance built on the high-capacity NG520 platform to serve complex enterprise network topologies requiring high port density and interface segmentation. Supporting 300 users, 1,500 devices, and 200k–300k concurrent connections, it delivers 2.1 Gbps firewall throughput and 1.3 Gbps UTM throughput.
Combining eight onboard 2.5GbE RJ45 ports (with 2-segment LAN bypass) with NIN-module port expansion and daughter-board copper/SFP options, the NG521 consolidates VLAN routing, DMZ zones, and multi-ISP failover into a single 1U rackmount appliance.
